非线性薄膜方程的差分迭代求解

o the nonlinear partial difference equation of membrane and the like, in this paper, a new solution is put forward. That is first to neglect the effect of the nonlinear part, or to give the nonlinear part an initial value making it known. The original nonlinear equation linearized this way is to be solved by differential method or other linear methods. The linear result found this way is put into the nonlinear part to make it known again. The linearized equation can be solved as above once more. Repeat the iteration until it converges to a satisfied result. A solution to the original nonlinear equation is obtained by the iteration process finally.
